邮政JSON字符串到网页API Windows应用商店8.1 [英] Post Json string to Web Api Windows Store 8.1

问题描述

使用Web客户端去precated和莎尔preST不适用于Windows 8.1的工作，我需要我的JSON字符串传递到Web API。

  

字符串JS = @[{用户名：jerin，用户id：一}];

  
  

VAR baseAddress =htt​​p://epub3.in/sample/android%20webservice/webservice/insertuser.php/;

 的HttpClient HttpClient的=新的HttpClient（）;
         HttpClient的HttpClient的=新的HttpClient（）;
        httpClient.BaseAddress =新的URI（baseAddress）;
        httpClient.DefaultRequestHeaders.Accept.Clear（）;
        httpClient.DefaultRequestHeaders.Accept.Add（新MediaTypeWithQualityHeaderValue（应用/ JSON））;
        尝试
        {
            HTT presponseMessage响应= httpClient.PostAsync（，
                新的StringContent（
                    JS，
                    Encoding.UTF8，
                    应用/ JSON））结果。
              串SD = response.IsSuccessStatus code.ToString（）;}
 

现在这里baseaddress是具有URL地址字符串。但是，即使我得到IsSuccessStatus code为真没有被输入了JSON。

而我应该看到在这个 链接

Android团队正在张贴，他们的PARAMS值为

  

usersJSON = [{username的：jerin，用户id：3}]

据@乔恩的答案我编辑我的code，其中我现在用Windows.Web.http而是OS System.Net.Http它仍然没有上传

  Windows.Web.Http.HttpClient的HttpClient =新Windows.Web.Http.HttpClient（）;
        Windows.Web.Http.Htt prequestMessage味精=新Windows.Web.Http.Htt prequestMessage（新Windows.Web.Http.HttpMethod（POST），新的URI（baseAddress））;
        msg.Content =新HttpStringContent（（JS））;
        msg.Content.Headers.ContentType =新HttpMediaTypeHeaderValue（应用/ JSON）;
        Windows.Web.Http.Htt presponseMessage响应=等待httpClient.SendRequestAsync（MSG）.AsTask（）;
 

解决方案

尝试使用的HttpClient从Windows.Web.Http命名空间：

 的HttpClient HttpClient的=新的HttpClient（）;
            HTT prequestMessage味精=新HTT prequestMessage（新列举HTTPMethod（POST），新的URI（baseAddress））;
            msg.Content =新HttpStringContent（JS）;
            msg.Content.Headers.ContentType =新HttpMediaTypeHeaderValue（应用/ JSON）;
            HTT presponseMessage响应=等待_httpClient.SendRequestAsync（MSG）.AsTask（）;
 

With webClient deprecated and SharpRest not working for Windows 8.1 I need to pass my json string to a web api.

string js =@"[{""userName"":""jerin"",""userId"":""a""}]";

var baseAddress="http://epub3.in/sample/android%20webservice/webservice/insertuser.php/";

        HttpClient httpClient = new HttpClient();
         HttpClient httpClient = new HttpClient();
        httpClient.BaseAddress = new Uri(baseAddress);
        httpClient.DefaultRequestHeaders.Accept.Clear();
        httpClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
        try
        {
            HttpResponseMessage response =  httpClient.PostAsync("",
                new StringContent(
                    js,
                    Encoding.UTF8,
                    "application/json")).Result;
              string sd = response.IsSuccessStatusCode.ToString();}

Now here baseaddress is a string which has url address. But even though I am getting IsSuccessStatusCode as true the json is not being entered.
and I am supposed to see the entered result in this link
Android team is posting where their params value is

usersJSON=[{"userName":"jerin","userId":"3"}]

According to @Jon's answer I edited my code where instead os System.Net.Http I am now using Windows.Web.http but its still not uploading

        Windows.Web.Http.HttpClient httpClient = new Windows.Web.Http.HttpClient();
        Windows.Web.Http.HttpRequestMessage msg = new Windows.Web.Http.HttpRequestMessage(new Windows.Web.Http.HttpMethod("POST"), new Uri(baseAddress));
        msg.Content = new HttpStringContent((js));
        msg.Content.Headers.ContentType = new HttpMediaTypeHeaderValue("application/json");
        Windows.Web.Http.HttpResponseMessage response = await httpClient.SendRequestAsync(msg).AsTask();

解决方案

Try using the HttpClient from the Windows.Web.Http namespace:

            HttpClient httpClient = new HttpClient();
            HttpRequestMessage msg = new HttpRequestMessage(new HttpMethod("POST"), new Uri(baseAddress));
            msg.Content = new HttpStringContent(js);
            msg.Content.Headers.ContentType = new HttpMediaTypeHeaderValue("application/json");
            HttpResponseMessage response = await _httpClient.SendRequestAsync(msg).AsTask();
